Welcome to Windows 7 Forums. Our forum is dedicated to helping you find support and solutions for any problems regarding your Windows 7 PC be it Dell, HP, Acer, Asus or a custom build. We also provide an extensive Windows 7 tutorial section that covers a wide range of tips and tricks.

as the title suggest I have the quite common (based on my research in the past couple of days) boot issue with Win7 pro 64, my XP works fine (Dual boot).
I have tried almost everything and I am at my wits end. I would be very grateful for any suggestions.
I've read hundreds of forums, nothing works for me

This is what I tried:
- the startup repair of course from win7 disc (usually it says it cant repair, sometimes it can but no change after restart). tried that xxx-times, with reboots in between and even with some command in the console
- bootrec fixes, bcdrebuilding - I tried virtualy every option here, order of commands etc. still nothing
- bcdedit I tried changing the drives (again basicaly every possibility), even though based on the forums it was correct in the beginning. Didn't solve anything so restored the original bcd
- chkdsk with all parameters - some minor corrections in free space, still nothing
-sfc /scannow - no error
-copied several versions of the winload.exe (from different dirs in my win folder) -still nothing, tried from dif. win7 install, still nothing, so again restored original
-also tried activate partition according to some it worked, didn't help me
- tried about 10 other things/commands -cant even remember them all, still nothing
- tried just with the new hdd connected, but I believe I have the boot manager/loader or stg on the older HDD with xp so didn't work (bcdedit confirms that). I tried removing the xp altogether by rebuildbcd but still returns the winload error.

This is my pc situation and how this occured:
- two windows on separate HDDs. Win XP is on older HDD, I bought a new HDD and win 7, installed on the new disk, no issues, dualboot worked fine.
- worked for week or two then just turn off my pc, turn on the next day and I have this error.
- XP works no problem - using now
- I cant get to advanced boot options for some reason (safe mode, last working config etc), if I press F8 either before dualboot screen or during, it returns the winload error. The only thing available is the hw memory check and that doesn't solve anything. And I'm sure F8 is the correct button for my pc as it worked in the past and manual confirms this.
-I can boot from the win7 disc but the repair there, nor the many suggested commands do not work

note: at the beginning the command /scanos didn't find any win installs - now it finds one the win7, even though win XP still works just fine! during some of the cmds I found on forums it started seeing the win7 installation, but that's about all the progress I made.

Also if the solutions ruins XP I don't really care, I just want the 7 to work and XP for some data.
I'm NOT doing a clean install, otherwise I'm willing to try pretty much everything... I even downloaded one sw that claimed to solve this, ran it in XP but of course it started fixing xp - and I couldn't change it there.

I've seen the EASYRE sw but after new hdd and win7 it's a bit expensive for me.

Honestly if anyone can solve this, I will write a song about you..

P.S.:sorry for mistakes in English, I'm not a native speaker, but you don't have to talk down to me, I can handle it.

Thanks for the reply! My apologies, the error is actually with "e" at the end. So it's 0xc000000e.
Sorry for that, anyway I tried that already, didn't help. With the exception of the EasyRE as mentioned, as I can not afford it right now

Also, my boot from win7 disc, from the moment I press key to boot from cd/dvd to the point where the screeen with language selection and time sett. appears it takes about 15-20 minutes, is that normal? Doesn't seem to me..

Not normal at all. When you put your Win 7 disk in, after a few seconds you should see a black background and a lot of fines loading for about 15 seconds and the Win 7 screen should be on in no more than 30 seconds. Have you got a Windows disk that you purchased or did you download it from a site? If you downloaded from a site, I would suggest to do it again and burn at no more than 4X. Even if you did buy the Win 7 disk, at this point try a download Windows 7 Direct Download Links, Official Disk Images from Digital River from here and burn the .iso at no more than 4X and try a reinstall. You need to be sure and pick the correct language and the correct Win 7 version (Home Premium, Pro Etc.) and either 32-bit or 64-bit.

I thought so... it's a purchased disk - install disk. I'm downloading a repair disk now, just in case there are slight differences or the repair disk can actually repair it, unlike the install disk. I have win7 pro 64 bit, and dowlnoading the corresponding repair cd. Will try it shortly

I read somewhere (on the 100 pages I visited) that it is damaged bootmgr (this long boot from cd) and I should delete it and autorepair would replace it...do you think that's a good idea?
I tried searching more about this, but the I can't narrow the search criteria to have some relevant results, so not sure.
Anyway, since I have two OS on two HDDs, I'm not sure what to delete... the correct boot manager should be on C: I believe (the XP disk that was present befrore win 7 install on new HDD) and bcdedit shows bootmgr as on partition=C: ... tried changing that to the Windisk but no change. Both disks have the bootmgr file and both files are exactly the same (size, change date) - but that might have something to do with the 1000 repairs I tried already.

Btw, the /scanos command can't see any win install again. Though the win disk boot shows the install and I still have working dual boot (XP works). Also tried switching active partitions via diskpart commands - tried each one while setting the other inactive - didn't help.

But I discovered one thing I believe might be important - the diskpart showed only one partition for each disk. ie C: has only one partition and so does D:.... Shouldn't there be something like system/boot partition on each disk? If so how do I restore it? correct it?

Ok so I tried the repair disk, the boot was faster, I'd say 5 minutes - here the language option popped up right away, with install disk I wait for it for 5 minutes with the blue background (is it because it contains install as well?). Do you still think I should download the install disk anew? The one I have I installed the win7 from it 2 weeks ago without a problem (it's new) and it doesn't have a single scratch.
The startuprepair from the repair disk didn't repair it either - "missing OSloader" everytime (3x).

When you say try reinstall, what do you mean? Like I said clean install is not an option right now. I can't install (upgrade) from the install disk boot to the same disk as it says something about disk being used and I should install from the Win7-but I can't boot there. Friend who works with pcs told me if I install from XP, I will lose all data...is it not true? If not, I will reinstall immediately from XP if it will keep my data/registries etc.

What do you men the "language option popped up"? Did you install the correct language? == You have the XP on one HDD and want to install Win 7 on another correct? Why is Clean Install not an option? That is the way to go. You have exhausted every other option at this time. Boot from the Win 7 disk. This means put the disk in your DVD drive, shut down computer and boot again. This should boot from the DVD and allow you to install Win 7 on the HDD that you desire. It will not bother any info that you have on other HDD or any other partition on the same HDD. From what you said, I don't think you are booting from the DVD. That is why you are getting the error "can't install (upgrade) from the install disk boot to the same disk as it says something about disk being used and I should install from the Win7-but I can't boot there". Boot from the DVD and see if you can install Win 7. Here is a tutorial Clean Install Windows 7 Let us know how you are progressing.

First as far as the clean install - I do not want to install a new version of Win7, I want to repair the existing one which worked just fine (briliantly in fact) for 2 weeks. By the language option I meant the window where you choose your lang, keyboard etc like on the screen in the link you sent - when booting from dvd. I have XP on one HDD and Win7 on another, worked just fine for week or two, suddenly with no changes this boot error. Sorry for the confusion.
I am not a complete amateur, I know how to boot from cd/dvd, i set it in the bios and pressed the key to boot from cd and exactly the screens as in the tutorial you linked (thanks anyway). I also noted how many changes I tried to make via the console, startup repair etc(see first post:what i tried), some of which is accessible only through this boot right?
That's exactly where it says I can't install it etc.
The "disk is used" message also showed in the dvd boot console when I tried either chkdsk or sfc /scannow, not sure which one, but I could confirm to proceed...or at least in what I believed to be a dvd boot console, you got me seriously confused now.
Anyway if I follow the links instruction I get exactly the error I mentioned...and it looks exactly the same as in the link as well.

My apologies if I did not make that clear in the previous posts.
If I'm still misunderstanding you, just tell me, I'll try my native language forum and return my university degree in English language and literature But my win7 is English and I prefer English nowadays - especially when searching for solutions to problems on the internet. Also one reason why I chose Eng version.
Either way any feedback is truly appreciated! Thanks for your time.

add. I will try again and write down the message that pops up exactly.
